摘要
提出了一种无位置传感器的开关磁阻电机的初始位置检测方法,即依次给定子相注入电压脉冲,利用各相测试电流与定子电感和转子位置的关系,确定转子初始位置及其相应初始导通相,从而实现转子处于任何位置时的无反转起动,对不允许转子反转的某些应用场合具有较大的实用价值。仿真和实验结果验证了该方法的可行性。
A sensorless method for determining rotor position for switched reluctance motors is proposed,which detected the rotor initial position and decides the initial starting phases through the relationship of the rotor position, stator winding inductance and currents from the injected testing voltage pulse into phases of SRM. And the start of position sensorless SRM without reversing can be achieved,which means SRM can be practicable in some reversingforbidden applications.
